\"1775The 1775 Sprocket Drive Wheel is purpose-built to engage directly with the 1775-series plastic modular conveyor belt, delivering torque from the drive shaft to the belt surface with minimal slip and consistent pitch engagement. Manufactured from engineering-grade acetal (POM) or polyamide depending on load requirements, each sprocket is dimensionally machined to tight tolerances \u2014 Bore (RB) options of 25, 30, 35 and 40 mm ensure compatibility with the shaft sizes most commonly found in UK conveyor installations. Whether you are retrofitting an ageing food production line in Manchester, commissioning a new packaging cell in the West Midlands, or replacing worn drive components in a cold-store logistics hub in Yorkshire, the 1775 Sprocket Drive Wheel slots into existing frameworks without costly adaptation work. The bolt-hole pattern and hub width (29 mm inner, 44 mm outer hub face) are kept consistent across the full tooth-count range, so you can switch from 16T to 21T without changing your shaft arrangement \u2014 a practical advantage when adjusting belt speed ratio or belt tracking.<\/p>\n

Why UK Engineers Specify the 1775 Drive Sprocket<\/h2>\n
\n
\n
\u2699\ufe0f<\/div>\n

Precision Machined Bore<\/strong><\/p>\n

Four standard bore sizes (25 \/ 30 \/ 35 \/ 40 mm) machined to H7 tolerance for direct shaft mount \u2014 no sleeve adapters, no field reaming.<\/p>\n<\/div>\n

\n
\ud83e\uddea<\/div>\n

Food-Safe Polymer Construction<\/strong><\/p>\n

Acetal (POM) and polyamide options comply with EU 10\/2011 and UK food contact material regulations \u2014 critical for BRCGS-certified food sites.<\/p>\n<\/div>\n

\n
\ud83d\udd01<\/div>\n

Cross-Compatible Tooth Counts<\/strong><\/p>\n

16T, 19T, 20T and 21T variants share identical hub geometry, making speed-ratio changes a shaft-key swap rather than a full head-shaft rebuild.<\/p>\n<\/div>\n

\n
\ud83c\udf21\ufe0f<\/div>\n

Wide Temperature Window<\/strong><\/p>\n

Operates reliably from -30 \u00b0C (blast-freeze) to +80 \u00b0C (hot-wash CIP cycles), covering practically every UK cold-chain and processing scenario.<\/p>\n<\/div>\n

\n
\ud83d\udee1\ufe0f<\/div>\n

Corrosion-Free by Design<\/strong><\/p>\n

No rust, no pitting, no surface coatings to flake off. Ideal where stainless-steel sprockets cause galvanic issues or where washdown chemicals are aggressive.<\/p>\n<\/div>\n

\n
\ud83d\udce6<\/div>\n

Low Noise & Self-Lubricating<\/strong><\/p>\n

Polymer-on-polymer engagement is inherently quieter than metal sprockets and requires zero lubrication \u2014 cutting maintenance visits and reducing product contamination risk.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

Operating Principle, Materials & Application Scenarios<\/h2>\n

Drive power enters the conveyor system at the head shaft and transfers through the sprocket’s precision-cut tooth profile directly into the hinge rods of the 1775-series modular belt. Because the tooth geometry is matched exactly to the belt’s 1.75-inch (44.45 mm) pitch, there is no longitudinal slippage during engagement \u2014 each tooth seats cleanly into the belt pocket and releases cleanly on the return side. This positive-drive action eliminates the belt tensioning headaches associated with friction-drive flat belts, and it means the sprocket operates effectively even under variable load profiles \u2014 the sort of intermittent loading typical in UK poultry processing lines, automotive parts washing tunnels, or biscuit cooling conveyors.<\/p>\n

Acetal (POM) is the default material: it offers an excellent combination of dimensional stability, high surface hardness and low moisture absorption, making it the right choice for food-contact, washdown and moderate-temperature environments. Where the operating temperature regularly exceeds 60 \u00b0C \u2014 in-line tunnel ovens, heat-seal stations, or high-pressure steam CIP systems \u2014 we supply the polyamide (PA6 or PA66) variant, which retains its mechanical properties at elevated temperatures while accepting a small degree of moisture absorption without compromising fit on the shaft bore. Both polymers are pigmented to the customer’s choice of colour (natural, blue, or black) to support in-line visual quality checks \u2014 a practical feature appreciated by QA teams on UK food manufacturing sites that must demonstrate traceability under BRC and SALSA audit conditions.<\/p>\n

\n
\n

Food & Beverage Processing<\/strong><\/p>\n

Poultry, fish filleting, bakery, dairy \u2014 washdown-safe, no lubricant contamination risk.<\/p>\n<\/div>\n

\n

Packaging & Palletising<\/strong><\/p>\n

Case erectors, bottle unscramblers, shrink-wrap tunnels across UK FMCG facilities.<\/p>\n<\/div>\n

\n

Cold Chain & Logistics<\/strong><\/p>\n

Blast-freeze conveyors, chilled sortation lines, ambient distribution centres.<\/p>\n<\/div>\n

\n

Automotive & General Manufacturing<\/strong><\/p>\n

Parts washing, assembly transfer, paint pre-treatment lines where corrosion resistance matters.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Customer Success: Reducing Drive Maintenance Downtime by 60%<\/h2>\n

UK Poultry Processing \u2014 West Yorkshire, England<\/p>\n

\n

A medium-sized poultry processing plant in Wakefield was running stainless-steel sprockets on their 1775-series chiller conveyors. Despite regular greasing schedules, the sprockets were corroding at the bore interface and wearing unevenly within six months of service \u2014 a combination of the ammonia-heavy refrigerant atmosphere and the aggressive chlorinated washdown regime. Unplanned changeovers during production shifts were costing the facility roughly 14 hours of downtime per quarter, each one requiring a permit-to-work and two maintenance engineers.<\/p>\n

After switching to the 1775 Sprocket Drive Wheel<\/strong> in POM blue across all seven conveyor head shafts, the site recorded zero unplanned sprocket-related stoppages over the following 12 months. The blue colouring satisfied their metal-detection-equivalent visual check protocol, and the corrosion-free polymer eliminated the ammonia-induced pitting that had been accelerating wear on the previous steel components. Maintenance intervals moved from quarterly to annual, and the total parts cost \u2014 including the initial switch-over \u2014 was recovered within the first four months through saved downtime alone.<\/p>\n<\/div>\n

“We’ve trialled several makes of plastic sprocket on our fish processing lines in Aberdeen and these are the only ones that have held dimensional tolerance after two years of continuous three-shift operation. Bore fit has not opened up at all.”<\/p>\n

\u2014 Engineering Manager, Seafood Processing Facility, Aberdeen, Scotland<\/strong><\/p>\n<\/div>\n

\n

“Lead time was critical \u2014 we needed 28 sprockets to get a line back into production after an emergency. The team had them machined, quality-checked and on a next-day pallet from our order placed at 10am. That kind of response is genuinely rare with specialist components.”<\/p>\n

Custom Manufacturing & Factory Capabilities<\/h2>\n

Our production facility operates a dedicated polymer machining line with CNC turning centres and milling cells capable of producing non-standard sprocket configurations from short-run batches upward. If your conveyor system uses a shaft diameter outside the standard 25\u201340 mm bore range, requires a keyway or set-screw flat, needs a split-hub design for mid-shaft installation, or uses a tooth count not listed in the standard catalogue (anything from 12T to 30T is achievable in 1775 series geometry), our application engineers will produce a 2D drawing for approval before any material is cut. Minimum order quantities for custom work are kept low \u2014 we understand that a single-line facility may need just four or six sprockets per drive shaft and we accommodate that without the tooling surcharges typical of large production foundries.<\/p>\n

We also offer consignment stock agreements for UK distributors and OEM conveyor builders: pre-agreed quantities of fast-moving sizes (typically 16T and 20T in 30 mm bore) held at your facility on a call-off basis, so your engineers never face a production halt waiting for a sprocket. Contact our sales team to discuss the arrangement that suits your operation.<\/p>\n

You can order directly from this page or email sales@plastic-modular-belt.com<\/a> with your bore size, tooth count and quantity. We despatch to all UK mainland addresses and can arrange freight to Northern Ireland and Scottish Highlands.<\/div>\n<\/div>\n
\n
What is the price of a 1775 plastic modular belt drive sprocket and do you offer volume discounts for UK buyers?<\/div>\n
Unit pricing varies by tooth count, bore and material. We offer tiered volume pricing from 10 pieces upward \u2014 useful for facilities holding a stock of common sizes on the shelf for rapid changeover. Request a quote with your specifications for a firm price.<\/div>\n<\/div>\n
\n
How do I know which tooth count \u2014 16T, 19T, 20T or 21T \u2014 is correct for my UK conveyor application?<\/div>\n
The correct tooth count depends on your required belt surface speed and your head shaft RPM after gearbox reduction. A higher tooth count gives a larger pitch circle and therefore slightly higher belt speed at the same shaft speed. Share your motor, gearbox and target belt speed with us \u2014 our engineers will confirm the right selection free of charge.<\/div>\n<\/div>\n
\n
Is the 1775 Sprocket Drive Wheel food-safe and compliant with UK food contact material regulations?<\/div>\n

\n
Can I get a custom bore size or keyway machined into the 1775 drive sprocket for a non-standard shaft?<\/div>\n
Yes. Send us a shaft drawing or simply the diameter, keyway width and depth. We will produce a 2D sprocket drawing for your approval before machining \u2014 typical lead time for custom-bore work is 10 working days from drawing sign-off.<\/div>\n<\/div>\n
\n
How long does delivery of the 1775 Sprocket Drive Wheel take to a UK address?<\/div>\n
Standard catalogue sizes are typically despatched within 2\u20135 working days by road freight. For genuine emergency breakdowns, contact us by phone or email as early in the day as possible \u2014 we will advise on express machining and same-day or next-day courier options.<\/div>\n<\/div>\n
\n
Which supplier in the UK stocks plastic modular belt sprockets compatible with the 1775 belt series?<\/div>\n
We supply the complete 1775 system \u2014 drive sprockets, idler wheels<\/a> and the 1775 Gapless Sideflex belt<\/a> itself \u2014 to UK food processors, packaging OEMs and logistics operators.
